Eidos Announces Use Of Next Generation Unreal Engine

Ion Storm Austin To Use Technology In Their Upcoming Titles

San Francisco, CA. (June 20, 2001) - Eidos Interactive, (NASDAQ: EIDSY), a
leading worldwide interactive entertainment publisher, today announced that
ION Storm Austin has been granted a license to use Epic Games' next generation
Unreal Engine in their upcoming games. ION Storm Austin used an earlier
version of the Unreal Engine technology in the creation of the award winning,
genre-bending, first person shooter, Deus Ex.

"Everyone at Epic is extremely proud of Deus Ex and the tremendous job
the ION Storm team did in creating an innovative and deep gameplay experience
using our technology," says Mark Rein, Vice President of Epic Games Inc.
"We're excited that they're now developing games with our next generation
Unreal Engine technology. ION Storm Austin represents the absolute highest standards
in game design and we're thrilled to play a role in their very exciting future."

"The decision to use the original Unreal Engine as the foundation for
Deus Ex was one of the best decisions we made," states Warren Spector,
project director on Deus Ex and Studio Director for ION Storm Austin. "Unreal,
and the Unreal toolset, freed us to focus on design issues rather than technology
which, given the response of public and press to the game, seems to have been
a good thing! Looking ahead to future projects, the next generation Unreal Engine
offers us even more power, even better tools and a multiplatform solution."

The Unreal Engine, created for Epic's revolutionary 3D first-person Unreal
computer game, provides programmers with a complete solution for software development
-- from design and Artificial Intelligence (AI) to texture mapping and networking.
Recently, Epic announced several new features that made the updated Unreal Engine
the obvious choice for ION Storm Austin, including a hardware-accelerated, large-scale
terrain system; hardware brushes for quickly creating scenes 100 to 200 times
more detailed than current levels; and texture compression allowing for enormous,
photorealistic textures up to 2048x2048.

"Unreal allowed the Deus Ex programmers to add in all the rich RPG features
the team wanted in minimal time." States Harvey Smith, Lead Designer on
Deus Ex and now a Project Director for Ion Storm Austin. "Also, the Epic
team was super helpful to us, sharing a wealth of high-impact technological
and visual-aesthetic technique."

The Deus Ex team's experience with Unreal was important to Randy Smith, another
of Ion Storm Austin's Project Directors: "The Unreal Engine is the perfect
starting point for development. With its rendering power we can craft environments
in higher detail than ever before, and its flexibility allows us to shape it
into an ideal tool for implementing our unique gameplay."

More information on ION Storm Austin's use of the next generation Unreal
Engine can be found in the August issue of PC Gamer magazine due on shelves
July 15th.
